GNU GENERAL PUBLIC LICENSE
Version 3, 29 June 2007
Copyright (C) 2007 Free Software Foundation, Inc. <http://fsf.org/> Everyone is permitted to copy and distribute verbatim
copies of this license document, but changing it is not allowed.
Pream ble
The GNU General Public License is a free, copyleft license for software and other kinds of works.
The licenses for most software and other practical works are designed to take away your freedom to share and change the works. By
contrast, the GNU General Public License is intended to guarantee your freedom to share and change all versions of a program--to
make sure it remains free software for all its users. We, the Free Software Foundation, use the GNU General Public License for most
of our software; it applies also to any other work released this way by its authors. You can apply it to your programs, too. When we
speak of free software, we are referring to freedom, not price. Our General Public Licenses are designed to make sure that you have
the freedom to distribute copies of free software (and charge for them if you wish), that you receive source code or can get it if you want
it, that you can change the software or use pieces of it in new free programs, and that you know you can do these things. To protect
your rights, we need to prevent others from denying you these rights or asking you to surrender the rights. Therefore, you have certain
responsibilities if you distribute copies of the software, or if you modify it: responsibilities to respect the freedom of others. For example,
if you distribute copies of such a program, whether gratis or for a fee, you must pass on to the recipients the same freedoms that you
received. You must make sure that they, too, receive or can get the source code. And you must show them these terms so they know
their rights. Developers that use the GNU GPL protect your rights with two steps: (1) assert copyright on the software, and (2) offer you
this License giving you legal permission to copy, distribute and/or modify it. For the developers’ and authors’ protection, the GPL clearly
explains that there is no warranty for this free software. For both users’ and authors’ sake, the GPL requires that modified versions
be marked as changed, so that their problems will not be attributed erroneously to authors of previous versions. Some devices are
designed to deny users access to install or run modified versions of the software inside them, although the manufacturer can do so. This
is fundamentally incompatible with the aim of protecting users’ freedom to change the software. The systematic pattern of such abuse
occurs in the area of products for individuals to use, which is precisely where it is most unacceptable. Therefore, we have designed this
version of the GPL to prohibit the practice for those products. If such problems arise substantially in other domains, we stand ready to
extend this provision to those domains in future versions of the GPL, as needed to protect the freedom of users. Finally, every program
is threatened constantly by software patents. States should not allow patents to restrict development and use of software on general-
purpose computers, but in those that do, we wish to avoid the special danger that patents applied to a free program could make it
effectively proprietary. To prevent this, the GPL assures that patents cannot be used to render the program non-free. The precise terms
and conditions for copying, distribution and modification follow.
TERMS AND CONDITIONS
0.
Definitions.
“This License” refers to version 3 of the GNU General Public License.
“Copyright” also means copyright-like laws that apply to other kinds of works, such as semiconductor masks.
“The Program” refers to any copyrightable work licensed under this License. Each licensee is addressed as “you”. “Licensees” and “
recipients” may be individuals or organizations.
To “modify” a work means to copy from or adapt all or part of the work in a fashion requiring copyright permission, other than the
making of an exact copy. The resulting work is called a “modified version” of the earlier work or a work “based on” the earlier work.
A “covered work” means either the unmodified Program or a work based on the Program.
To “propagate” a work means to do anything with it that, without permission, would make you directly or secondarily liable for
infringement under applicable copyright law, except executing it on a computer or modifying a private copy. Propagation includes
copying, distribution (with or without modification), making available to the public, and in some countries other activities as well.
To “convey” a work means any kind of propagation that enables other parties to make or receive copies. Mere interaction with a
user through a computer network, with no transfer of a copy, is not conveying.
An interactive user interface displays “Appropriate Legal Notices” to the extent that it includes a convenient and prominently visible
feature that (1) displays an appropriate copyright notice, and (2) tells the user that there is no warranty for the work (except to the
extent that warranties are provided), that licensees may convey the work under this License, and how to view a copy of this License.
If the interface presents a list of user commands or options, such as a menu, a prominent item in the list meets this criterion.
1.
Source Code.
The “source code” for a work means the preferred form of the work for making modifications to it. “Object code” means any
nonsource form of a work.
A “Standard Interface” means an interface that either is an official standard defined by a recognized standards body, or, in the case
of interfaces specified for a particular programming language, one that is widely used among developers working in that language.
The “System Libraries” of an executable work include anything, other than the work as a whole, that (a) is included in the normal
form of packaging a Major Component, but which is not part of that Major Component, and (b) serves only to enable use of the work
with that Major Component, or to implement a Standard Interface for which an implementation is available to the public in source
code form. A “Major Component”, in this context, means a major essential component (kernel, window system, and so on) of the
